Welded combined T-shaped steel column correcting device and method

Abstract

The invention discloses a welded combined T-shaped steel column correcting device and method. The correcting device is composed of multiple correcting units which are on the same straight line. Each correcting unit comprises a platform support, two L-shaped clamps and a jack. Each platform support is formed by welding two stand columns and a cross beam. A vertical beam is arranged on the upper surface of each cross beam, wherein each vertical beam is perpendicular to the corresponding cross beam. The two ends of each vertical beam are provided with two rectangular connecting blocks, wherein every two rectangular connecting blocks are parallel with the corresponding cross beam. Each connecting block is uniformly provided with multiple threaded holes. Each L-shaped clamp is integrally formedby a transverse plate and a vertical plate. Each transverse plate is provided with threaded holes matched with the threaded holes in the connecting blocks. Threaded connecting pieces penetrate the threaded holes in the transverse plates and the threaded holes in the connecting blocks, so that the two L-shaped clamps are fixedly connected with the two connecting blocks correspondingly. Each jack is arranged between the corresponding vertical beam and a to-be-corrected welded H-shaped profile steel web plate. A base of each jack tightly jacks the corresponding vertical beam. The stroke end of each jack tightly jacks the corresponding to-be-corrected welded H-shaped profile steel web plate. The welded combined T-shaped steel column correcting device has the advantages of being simple in structure, easy to operate, low in cost, high in efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of building steel structures, and in particular relates to a straightening device and a straightening method for a welded combined T-shaped steel column. Background technique [0002] The welded combined T-shaped steel column is composed of welded H-shaped steel and welded T-shaped steel. The processing sequence is to process the welded H-shaped steel and welded T-shaped steel first, and use the flange straightener to straighten the welded H-shaped steel and welded T-shaped steel. The welded T-shaped steel is welded in the center of the web of the welded H-shaped steel. After welding, the two ends of the web centerline of the welded H-shaped steel will warp to the welding surface (ie, the direction of the T-shaped steel). Therefore, the welded H-shaped steel web after welding needs Correction, but this combination of steel columns is not easy to use existing equipment for correction. The traditional straigh...

The processing sequence is to process the welded H-shaped steel and welded T-shaped steel first, and use the flange straightener to straighten the welded H-shaped steel and welded T-shaped steel. The welded T-shaped steel is welded in the center of the web of the welded H-shaped steel. After welding, the two ends of the web centerline of the welded H-shaped steel will warp to the welding surface (ie, the direction of the T-shaped steel). Therefore, the welded H-shaped steel web after welding needs Correction, but this combination of steel columns is not easy to use existing equipment for correction

The traditional straightening method is to use a flame and a small jack to straighten manually. This method not only has low efficiency and high energy consumption, especially for composite steel columns with too thick plates and too narrow web and flange widths, the traditional straightening The method has no operation space
